London's international fish trade can be traced back 800 years to the medieval period, according to new research published today in the journal Antiquity.
The research, led by archaeologists from UCL, Cambridge and UCLan, provides new insight into the medieval fish trade and the globalisation of London's food supply.
Archaeologists analysed data from nearly 3,000 cod bones found in 95 different excavations in and around London. They identified a sudden...

In the Baltic Sea, two cod stocks evolve independently. Also the juveniles of two economically important flatfish species, flounder and plaice, live there within limited space. This is possible due to the irregular distribution of water masses of different salinity in this inland sea.

The escolar (Lepidocybium flavobrunneum) is a species of fish found in tropical to temperate waters 650 to 2,900 feet in depth, around the world. It is also known as the snake mackerel, walu and sometime sold as butterfish or white tuna.
It has been mislabeled in restaurants and fish markets as white tuna. In studies from 2010 to 2013, it was found that 84 percent of over 114 samples of tuna were actually escolar. However, the studies were conducted with no quality control so the accuracy...

The Atlantic Cod (Gadus morhua) is a well-known benthopelagic food fish belonging to the family Gadidae. It’s also commercially known as cod, coding, or haberdine.
Within the western Atlantic Ocean, cod has a distribution north of Cape Hatteras, North Carolina, and around both coasts of Greenland; in the eastern Atlantic, it is found from the Bay of Biscay north to the Arctic Ocean, including the Baltic Sea, the North Sea, Sea of the Hebrides, areas around Iceland and the Barents Sea....

The Antarctic Cod (Dissostichus mawsoni), also known as the Tootfish, is a species of fish of the family Nototheniidae. It produces antifreeze glycoprotein that allows it to live in the frigid waters off the coast of Antarctica. Its distribution range is generally below 65 degrees South. It is mainly caught in the Ross Sea in the austral summer but has also been recorded south of the Indian Ocean region, in the vicinity of the Antarctic peninsula, and near the South Sandwich Islands. Despite...

The Atlantic Saury (Scomberesox saurus) is found in the Atlantic Ocean, in the seas near Australia and the Mediterranean. These fish grow to about 13.75 inches long, although they can attain lengths of up to 20 inches long. They have beadlike jaws and a row of finlets behind the dorsal and anal fins. They feed on zooplankton and fish larvae. They are common prey to tuna, marlin, bluefish and cod. The Atlantic Saury live near the surface, and will sometimes jump above the surface.

The Malabar Grouper (Epinephelus malabaricus), also referred to as the Estuary Cod, Greasy Cod, Spotted River Cod or Estuary Rock Cod, is an Indo-Pacific species of fish in the family Serranidae. It is found in the Red Sea, south to South Africa, as far as Southeast Australia and south Japan. It is found as deep as 200 feet, in lagoons, mangrove swamps, reefs and sand bottoms.
The Malabar Grouper is one of the largest and most common cod found in tropical estuaries and on coastal reefs....
